The internet analog of buyer's remorse, wherein one comes to regret having clicked on a link of interest after they look up at the clock minutes or hours later and realize that they have invested an inordinate amount of time reading an article, playing a game, conversing with someone, looking at photos, etc. which they would not have spent had they resisted the impulse to "check it out"...

Upon looking up at the clock and realizing he'd spent the last 2 hours choosing the cuter kitten after clicking on the link his sister had emailed him Danny developed a strong feeling of clicker's remorse for not having resisted the urge to click on the link.
